1.2 General Safety
- This inverter is Transformerless design; there is no galvanic transformer to
isolate between DC and AC. Please ensure it fulfills the request of the PV
system design.
- Every PV string must be isolated from the earth.
Do not ground either side of the PV array!
- Grounding L1, L2, L3, or N terminal is prohibited; it could cause an imbalanced
residual current to damage the inverter and void the product warranty.
ATTENTION : NO GALVANIC ISOLATION
- Please read this manual in detail to get the correct instruction for the installation.
ATTENTION : INSTALL BY INSTRUCTION
The product is certified to operate in the industrial environment, which means its
design, verification, or production fulfill the safety requirement standard. To ensure
the PV system can operate well for the long-term and keep the danger of injury
or property loss away. Please follow the safety instruction in this manual to install
the product.
- M100A_280/283 and M110A_283 is a transformerless PV inverter with 8 MPP
tracking inputs, which converts the energy generated by the PV array to a
three-phase current via a high-efficient way and feeds into the utility grid.
- To ensure the inverter operates with high-performance, the PV array should be
compatible with the inverter (please refer to Chapter 3.5).
- The PV array with a parasitic capacitance to Ground may not exceed 10μF.
- Suitable for industrial environment.
- The inverter should be operated in regions that are approved by DELTA and
the grid operator.
